Complete extruder — 2012 December

The Hyena family v2

The campaign helped me get the manufacturing done and gather much feedback.
Which kickstarted the design of v1's successor!

Asymmetric tooth profile - Hyena v2

To come up with this tooth profile it had taken countless hours and numerous versions.

Did you think the hyena was a great product? Then you'll think v2 is the best product ever!

The v2 outperforms v1 by 220%. That means at a given force where v1 has already slipped and chewed up your filament, v2 is still pushing it through happily!

Specification

For the tech-savvy out there, here is the drawing:

Unified size

One of the main discoveries from the campaign was
that the four different sizes did more confusion than good.

The conclusion is to make one size with either a 5mm or 8mm bore.
It makes everyone's life easier and one size fits all!

Here is a picture to demonstrate this handy property:

Regular hyena adjusted — Hyena v2.0

This news itself would deserve a separate article, as it is a huge milestone.
For v1.0 announcement, read here, and for v1.1 read here.

The shorter, the better

You don't need worry about the length of your motor shaft. Or particular extruder design,
because the mini hyena was designed to the shortest length possible: 10mm!

One size fits all

A picture worth a thousand words:)

Mini hyena fits on either 5mm or 8mm motor shafts.

Final look

When the extruder is properly set up the hyena accumulates absolutely no plastic chips over time.

Here is a photo after two weeks of continous printing:

If there are some chips inside, clean the Hyena with a needle not a file.
Never use heat especially not a blowtorch.

Printing achievements

I should compile an another article, where we are currently quality-wise, since I teamed up with a professional graphic artist (hey QNLaca!:)).

Until that article, here is a photo for the impatients:

Hall of fame
